How to return multiple values in Python function. If you want to get multiple values at a time, use something like x, y = func()[2:4]. def f(): return 1, 2, 3 _, _, x = f() Solution 2: You can use x = func()[0] to return the first value, x = func()[1] to return the second, and so on. 1) Using Object: This is similar to C/C++ and Java, we can create a class (in C, struct) to hold multiple values and return an object of the class. In the below example myfunc returns maximum element, … We can use yield, in this case, to return multiple values one by one. Required fields are marked *. **kwargs: Receive multiple keyword arguments as a dictionary; Expand lists and dictionaries (Unpacking) Return value. A function is not required to return a variable, it can return zero, one, two or more variables. However, if you have to return a huge number of values then using sequence is too much resource hogging operation. Introduction to Python Return Value To make your code reusable, you tend to use functions if the same piece of code is utilized multiple times.

The name of the person is a key and their age is the corresponding value: This is how to write a function that returns a dictionary with a key/value pair: A list is similar to an array of items formed using square brackets, but it is different because it can contain elements of different types. The main things I had to watch was creation of the queue items and the firing of multiple threads. A class (in C, a struct) can be formed to hold several attributes and return a class object: Using Python 3.7’s data classes, this is how you can return a class with automatically added unique methods, typing, and other useful tools: See the official documentation for further clarity on data classes.
